Glibc 2.13 has now fixed the bug, but gnulib and glibc have diverged a while ago, so it's a bit of a project to backport all the changes (including this particular fix). I'm not sure when I'll get around to it, and welcome anyone else doing the sync first. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
